The degree of nonlocality introduced into the nucleus-nucleus interaction by the requirements of the Pauli principle is discussed on the basis of the properly orthogonalized equation of relative motion of the two nuclei, which is an equation for physical wave functions with a direct probability interpretation. Exact calculations of the kinetic energy exchange potential, the Coulomb exchange potential, and the pure nuclear exchange potential are performed for the ..cap alpha..-..cap alpha.. system. Even in this simple example, a variety of very different structures can be obtained for the nuclear exchange potential, depending on which nucleon-nucleon interaction is chosen.
